WAGON-BOX END GATE'.

Application filed March 1, 192,4. Serial No. 696,250.`

wagon box end gates and an object of the invention is to provide a comparatively cheap yet strong and durable end gate or door fora `wagon box, which can be easily and at small expense attached to the present types of wagon boxes, and which is arranged such that it is `grain tight when closed and canbe `quickly removed when desired.v f

A further Object is to construct a door or gatewhich does away with the tie rods at present in universal use.

l/Vith the above more important objectsv in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawings in which: f

Fig. 1 is an end view of a wagon `box equipped with my invention.

Fig. 2 is an enlarged detailed vertical sectional view at 2-2 Fig. 1, both door sections being closed. I

Fig. 3 is a view similar to Fig. 2 with the lower door section open.

Fig. 4L is a side view of part of the box.

Fig. 5 is a horizontal sectional view at Fig. 2.

Fig. 6 is an enlarged detailed face view of one of the side plates.

Fig. 7 is an end View of the latter plate.

In the drawing like characters of reference indicate corresponding parts in the several gures.

The wagon box 1 is of ordinary construction, embodyingV the bottom 2 and' sides 3 and f1, the bottom being carried at the rear end by. a cross beam 5 which has the ends thereof extended to receive the lower ends of angularly disposedside braces 6 and 7, which reinforce the sides.

The front of the box (not herein shown) is closed in the usual way and the rear in the present instance is closed by my door or gate which embodies an upper section 8 and a lower section 9. These sections are approximately of the same width and they are of such length that they just nicely i'lt within the sides of the box.

p To the inner faces of the box sides I secure a' pair of opposing, vertically extending similar strips 10, the upper ends of the strips being narrower `by the thickness of .the doorl than. the lower ends,iwhereby opposing horizontal stops 11, are formed, which provide rests for the lower edge of the upper door section. By observing Fig. 2 it willV be seen that the ends of the upper door section engage with the rear faces of the `upper portions of the strips, whilst the ends of the lower door section engage with the rear faces of the lower portions of the strips, and that the loweredge of the upper door section laps behind the upper edge of the lower door section. The door sections are both reinforced by applied cross bars 14 at their upper edges. The doors are swung from thesides of the wagon box in a manner shortly described.

To the upper corner of each door section I permanently ysecure a substantially T- shaped `plate 17 which has the horizontal outer .arm thereof cut away and shaped to provide a horizontally lying L-shaped member which provides a pivot spindle 18 and y a hooked shaped catch 19. The spindles are Of-such a length that they will passand extend slightly beyond the sides of the box, Y

and the spindles of the upper door section are adapted to enter and be rotatably carried by similar semi-circular bearings 2O and 21 formed at upper edges of the side plates 22 and 23, permanently secured to the sides of the box. The side plates are provided with horizontal flanges, and they, as well as the edges of the box sides, are cut away to permit the upper spindles to enter the bearings from the top. The bearings are semi-hub shaped, and the hooked ends of 'the catches are adapted to engage with the undersides of the bearings such preventing the raising of the door section, when the same is closed, and also preventing the door from coming out until the latter has been swung to a position parallel with the top of the box.

I desire to make the undersides of the bearings somewhat eccentric, as best shown in Fig. 6, so that the catches will draw the door section down when the section is being closed.

The spindles of the lower door section are pivotally carried by bearings of the same 'form as those provided for in the upper door section, the bearings being carried by side plates secured to the sides of the box. The ends of the box sides are horizontally slotted as indicated at 24 and 25 to allow the spindles of the lower door section to enter the bearings from the end of the box. The hooked shaped catches of the lower door section operate also on the under-sides of the latter bearings, which are also eccentric and are adapted to torce the lower door section downwardly to force it tightly against the bottom of the box when it is being closed.

lever Q6 is pivotally secured centrally to the lower edge of the lower door section. One end et the lever is provided with an ex tending catch 27 which is adapted in the horizontal position of the lever to enter a suitable slot 28 formed in the bottom ofthe box. A wearing plate 29 is located to the rear ot the lever and is fastened to the lower door section and said plate is supplied with an outstanding tongue 30 yforming a stop i" or the lever catch.

From the above description it will be obvious that I have provided a door or gate for a wagon box which dispenses entirely with the customary tie rods used, as when the door sections are closed, the sides of the box are held together by the hooked shaped catches and further both doors can be instantly removed or replaced.

Further it will be seen that when the door is closed it is grain tight as the ends of the llVhen one desires to unload his grain he simply releases the catch 27 by raising the lever, which action frees the lower door section to swing upwardly under the pressure of the grain. When desired both doors may be quickly'removed by swinging them to the horizontal position, raising the spindles out of the bearings and withdrawing them through the slots. The bottom door is withdrawn first and the top one afterwards.

Jany wagon box can be readily equipped with my door sections, by simply providing the sections and the ittings.

rEhis door arrangement also permits one to remove the top section of the wagon box, leaving the bottom section intact, the rear en-l ol the bottom section being closed by the lower door section.

VWhat l claim as my invention is:

The combination with a wagon box, of an end gate comprising a pair of upper and lower sections extending between and clos'- ing the end of the box, the lower edge of the upper section being lapped within the upper edge of the lower section, outstanding spindles permanently secured to the upper corners ot the sections, opposing pairs of upper and lower side plates secured to the sides of the box and providing semi-hub like bearings pivotally receiving the spindles, catches located at the ends of the spindles and provided with hooked ends adapted to underlie the hubs in the closing of the sections and means for releasably locking the lower section to the bottom of the box.
